“…The extra dimension opens new avenues for the existence of phenomena which are absent in the 1D case (see, e.g., [7][8][9][10]). Here we show that there exists a class of exact solutions of the ð2 þ 1ÞD SG equation which describes the propagation of distortions of an arbitrary shape along a Josephson vortex line.…”

We predict a new class of excitations propagating along a Josephson vortex in two-dimensional Josephson junctions. These excitations are associated with the distortion of a Josephson vortex line and have an analogy with shear waves in solid mechanics. Their shapes can have an arbitrary profile, which is retained when propagating. We derive a universal analytical expression for the energy of arbitrary shape excitations, investigate their influence on the dynamics of a vortex line, and discuss conditions where such excitations can be created. Finally, we show that such excitations play the role of a clock for a relativistically moving Josephson vortex and suggest an experiment to measure a time dilation effect analogous to that in special relativity.

“…The presence of a shape excitation reduces the average velocity hvi of a vortex line, for instance, in (b) the vortex in the left branch at t ¼ 80 is noticeably delayed from the vortex in the right branch of the Y junction. recently realized experimentally with a high-T c superconductor in the context of generation of Terahertz waves [10].…”

“…24 The effect of time dilation is to slow down the shape excitation when the vortex line reaches relativistic velocities. If the velocity of the shape excitation is smaller than some critical value, it will be directed to the left branch of the Y junction, as shown in the Fig.…”

“…Experimental confirmation of the proposed 14 use of this effect has also been obtained in a different, annular geometry for the main Josephson junction. 16 By selecting a suitable mode for flow of the transport current through the main Josephson junction this method of successive injection of vortices into the supplementary Josephson junction could be used to create trains with a large enough number of vortices in the supplementary junction.…”
